In the last decades decrease charakteristic species representation in the beech-oak forests slt Fageto-Quercetum. The aim of this work was to find out the nature of the changes in species composition and species diversity of the herb layer in the communities of Fageto-Quercetum group of forest types in the following year after the application of management treatments in experimental areas in the Slovenské stredohorie Mts.At 5 locations that consisted of 8 plots of 400m2 with different types of management (logging, raking, fertilization) we carried out phytosociological relevés on the 100m2 plots. We analyzed the changes in the undergrowth by using Juice 7.0 and Microsoft Excel ®, where we found a statistically significant change with the paired t-test.We found that a common species that responded positively to all types of management was the ruderal one-year-old species Moehringia trinervia, which significantly increased its frequency and coverage.Besides this species, other eutrophic taxa Erechtites hieraciifolius, Taraxacum sp., Urtica dioica have spread. On non-intervention areas, some nature-like species have spread like Primula veris and Campanula trachelium. The original oak-forest species and grasses did not expand significantly. The dominant cover of a typical species of oak forests Melica uniflora was only on the site Hrabiny, regardless of the type of management. The results suggest that a year after the application of the management, the ruderal, annuals, more nature distant species and synanthropic weeds have spread to the beech-oaks forests. A longer period is likely to be needed to extend the perennial species typical of the monitored communities.
